Here’s an interesting question posted on a milk manufacturer’s websites Q&A page.


I tried multiplying the 3 ends of a milk pack, but it won’t become 1 liter. Is there really 1 liter of milk in it? 


  1. The usual size  (inner size) of a 1000ml milk package in Japan is 70mm×70mm×194mm.
  2. The total would be  950.6ml, and does not reach 1000ml.



Reply from the manufacturer


  1. When the milk or other kind of beverage  is poured into the package, the inside wall of the package will be pressured
  2. As a result, 1000ml will can be packaged.


Are you satisfied with this reply? Why don’t you try it with a milk package at home?
